Hi people,

I searched the forum for information about buying a new hard drive, but all I came up with were posts about making a whole computer. None of them covered what I was looking for.

I've had the same 20gig HD for a few years now and I've decided I need more space. What I need to know is:

1.) Are Hard Drives generic in that they fit any motherboard, or do I need to buy one specifically for my motherboard? (I moved recently and haven't unpacked the motherboard box, so I don't have the specs handy)

2.) What does cache mean? I've looked at numerous hard drives and they all have different cache numbers (from 2mb to 8mb) and I don't what they mean.

3.) Does RPM really make that much of a difference? It seems that the only two options are 7200 and 10,000. I'm not in so much of a hurry that I need my data accessed thousandths of a second faster - is there anything else RPM does that should factor into my decision?

Thanks in advance for the help.
